dear "administrator/manager"
I have learned that you "want to buy" shelled pistachio (nut gereksiz) "could" you let us know the characteristics, "manner of packing" and "form of payment" of the nuts that you want "to buy". thank you
Manner of packing ve form of payment olarak da çevrilebilir o kısımlar, ekstra bir seçenek olarak yazdım onları.

The meaning is the same - I just changed it into more normal-sounding English. We don't say "dear administrator" or "manner of packing" in English.

I've made a few changes - I hope this is enough for turkishmiss and annabell_lee!
